The continuous wire 'rod mill is the most progressive apparatus for high quality wire rod production considering the productivity, close tolerance of products and so forth. In this paper, some fundamental studies, which have been carried out in a mill plant, are treated on the conditions of continuous wire rod rolling. In continuous wire rod rolling, any tension must be avoided between the adjacent stands as far as posssible. When a tension exerts in rolling, the wear of a roll pass decreases proportionally with the tension at the stand subjected to the forward pull, but it is not affected by it at the stand subjected to the backward pull. For a certain degree of tension the rolling torque and power consumption decrease at the stand subjected to the forward pull and increase at the stand subjected to the backward pull, but the sum of power consumptions of both stands is constant. The deformation of materials in the roll pass is affected by many factors, particularly by the resistance to deformation of materials due to the temperature. For the oval pass the radius of curvature of the pass must be determined in the optimum range. It is necessary to be careful about the rapid fall of the rolling temperature at a slow rolling speed. After rolling, the quality of materials is improved with selection of the adequate reeling temperature. To control this reeling temperature, the cooling guide tubes, which serve as the heat treating facilities, are satisfactorily installed.
